1.3 CONFIGURATION DEPENDING ON TYPE OF LAMPThe product is supplied with default settings that can be adapted to the different types of load. However, depending on the type of connection (3/4 wires or 2 wires, see paragraph 2 and 4.6) and the manu-facturing characteristics of the loads connected, some settings are recommended to optimise dimming and its range.

WARNING: If dimming is less than excellent, or there are problems with the power supply to the lamp, it isrecommended that:- if a two-wire connection has been used, a three or four-wire connection should be made (paragraph 2.1 or 2.2). Some types of loads are not suitable for this connection because of their manufacturing characteristics.

RESISTIVE LIGHTS, INDUCTIVE LOADS AND ELECTRONIC TRANSFORMERS:To ensure that it operates well with all types of load, the product is supplied with a default adjustableminimum brightness.To enjoy the full dimming range with these types of loads whose characteristics mean they usually even support low brightness values, just follow the "adjustable minimum brightness" procedure in paragraph 4.4.

LED LAMPSThe following procedure is not necessary but may optimise the operation of some LED lamps with manufactu-ring characteristics that mean they do not accept low brightness values during switch-on and dimming.

WITH SAVE FUNCTION NOT ON (see paragraph 4.5)- Set the desired minimum intensity value accepted by the type of lamp with wired or radio commands- Set this value as "adjustable minimum brightness", see paragraph 4.4

WITH SAVE FUNCTION ON (see paragraph 4.5)WARNING: this set-up is not recommended with LED lamps that are not suitable if you want to be able to adjust low brightness values.- Set the desired minimum brightness value accepted by the type of lamp with wired or radio commands- Give an OFF command- Give an ON command and check that the intensity supplied is enough to turn the light on- If the light doesn't come on, adjust the dimmer at a higher level of intensityWARNING: the light is off but the load is powered, use the "dimmer UP" command- Try to turn the light on and off again- Once the minimum intensity value that the lamp accepts is identified, set this value as "adjustable minimum brightness", see paragraph 4.4

WARNING: multiple buttons or loads can be connected using parallel wiring.

This is the standard connection. In fact with this type of wiring the control unit will always be powered,even with the load (e.g. bulb) disconnected.

As in the case of three-wire connections (paragraph 2.1), here again the control unit will always be powered. The neutral to the load will, however, be provided directly by the control unit itself.

This control unit is set up for different types of connection that allow greater flexibility to adapt to different system configurations. These differ in terms of the number of wires required to power the control unit and/or load (see also paragraph 4.6).

3 USE OF THE CONTROL UNIT

-WARNING: the connected devices must be buttonsThe device is set up to accept commands via wire by button in terminals 3 and 4.Should you want to control the load only via radio, it is not necessary to connect these devices for the control unit to work properly.The behaviour of the different keys is shown in the following table.

3 USE OF THE CONTROL UNIT

To control the loads via radio you must have compatible transmitters and therefore must carry out the associa-tion procedure, see paragraph 5.The transmitter's command modes depend on the model of transmitter used. If the transmitter is of a generic type, its operation depends on the way it is programmed (see paragraph 5, table 5.2b).If the transmitter is multifunctional, refer to the transmitter manual, to the paragraph entitled "commands sent by the transmitter", bearing in mind that it is a "dimmer" device.
